1. The problem statement, all variables and given/known data

DEFINE PRESSURE AT A POINT IN A FLUID AND SHOW THAT IT IS A SCALOR QUANTITY?


2. Relevant equations

I saw this in a recent paper and i am not too sure about how i should go about doing it..
Its a 7 mark question..

Any Ideas?

3. The attempt at a solution

That must be nasty exam if they expect you to reconstruct the demonstration that is in the introductory section of the typical fluid mechanics book. It's something about analyzing the forces on the face of an infinitely small polyhedron of fluid.
